[Greenbuilding] Cellulose settling/blowing

[Keith Winston]

Hi  Jefro,

Many, if not most, cellulose suppliers will supply, often for free, a 
blower when you buy a lot of cellulose. Beware: the cellulose to fill 
your entire 9.25" wall for an entire house will be a LOT of cellulose. 
You should look to get it delivered. In which case you might have to 
rent the blower separately. Which may not be a bad idea, since the 
rentals are sometimes better units.

Lowes often sell cellulose around here (Home Depot doesn't), and they'll 
give you a cheap rattly little blower. BUT: at one of their stores, they 
have a trailer they'll rent you for $40/day, with a REAL blower in it 
(and enough room for a fair bit of insulation, but still only 1/10 of 
your whole house, probably). You have to make sure you can park the 
trailer close enough that the hoses will reach everywhere you need to 
get to. Otherwise, most freebies and rental units are portable, and can 
be rolled into position (some are heavy, mine is around 200 lbs I think).

A medium-sized house might take a 40' trailer of cellulose. Have at 
least 2-3 assistants for blowing, it'll go easier. You probably won't 
have a recycler (a big vacuum) so someone will be hauling bags of 
overblow back out to the truck/blower regularly.
